1. This standard applies to steel ropes double stranding triggernometry one organic core.
2. The ropes are classified by signs
for the purpose:
gruzolyudskie — GL,
freight — G;
mechanical properties grades: VC, V, 1;
by coating the surface of wire rope:
from wire without coating,
galvanized wire depending on the surface density of zinc: C, W, coolant;
direction of lay:
right
left — L;
the combination of the directions of lay of the rope elements:
unilateral — O;
by way of lay:
prosrochena — N,
unwinding;
for precision manufacturing:
normal
high — T;
according to the degree of balance:
ratowanie — R,
neritani.
The ropes are manufactured in two versions — 1 and 2.

Notes:
1. The ropes, breaking strength of which is given to the left of the bold line are made of wire without coating and galvanized. Ropes of galvanized wire groups W and coolant diameter 50,0* marking groups 1370 N/mm(140 kgf/mm
), 40,5−46,5 mm marking group 1470 N/mm
(150 kgf/mm
), 30,0−46,5 mm marking groups 1570 N/mm
(160 kgf/mm
), 30,0−38.5 mm marking group 1670 N/mm
(170 kgf/mm
), 20,0−33,0 mm marking group 1770 N/mm
(180 kgf/mm
) versions 1 and 2 are made by agreement between manufacturer and consumer.
_______________
* The text of the document matches the original. — Note the manufacturer’s database.
The ropes, breaking strength of which is given to the right of the bold line are made of wire without coating. Allowed in coordination with the consumer manufacturing of ropes, galvanized wire.
2. For cables 1 core strand is made of steel rope wire, the tensile strength of which should correspond to the product group rope, and takes into account the total breaking strength of all wires in the rope.
3. For the execution of 2 strand core made of steel rope wire with the temporary resistance not more than 1370 N/mm(140 kgf/mm
) and in the calculation of the total breaking strength of all wires in the rope is not accepted.
4. The diameters of the ropes are rounded to whole numbers or to 0.5 mm.
